Radial photonic crystals (RPCs) are a class of microstructured
media that possess very particular electromagnetic
features. Their properties are driven by radially dependent permittivity
and permeability profiles that are also anisotropic. A two
dimensional RPC structure is designed and analyzed in order to
assess its principal characteristics. This is done through the study
of the dispersion diagram of the periodic multilayered structure
and also through the analysis of a finite size device. In the later
case, research is performed in view of possible applications of
RPCs as resonant devices and also when they are combined with
line sources. Finally, a device with reduced complexity is designed
and implemented by means of a microstructured resonator array.
This device is numerically analyzed and the comparison of two
independent models shows very good agreement. Potential use of
RPCs as frequency and location sensors is pointed out.[-]
